In my VPS (Hypervm/CENTOS 5.8 i686 virtuozzo) I need to add IP bans with comments ( http://spamcleaner.org/en/misc/iptables-comment.html ) When I type: iptables -A INPUT -s 222.111.111.111 -j DROP -m comment --comment "spammer123" I receive: iptables: Unknown error 4294967295 I research almost 2 hours but i find nothing, someone says "its a bug and you have to rebuild kernel!?" Does anyone know a solution or a different method for adding a comment or note ?
